This is quite simple.
If you don't think HCQ works.
Don't take it.
That is your right.
If you don't think I should have the right to take take it, and take steps to prevent me from having access to the drug… (you) crossed a line.
At that point you are imposing your will on me.
That will not stand.
Beware those who aim to impose their will on others. They are the danger.
